0.046 ohms

I've just checked it now and it read the resistance of a transformer correctly.

I'm going to have to work out the context of it doing this and repost

cowasaki:
Ok it's not working again....

Unless I'm missing something obvious.

I have a 56K resistor with probes attached either side.  First I'm measuring with a brilliant cheap multimeter the Owen B35T+. It measures the resistor at 56K5 which is confirmed using using Keithley 2100.  Then I haven't changed anything at all but simply moved the probes from the Owen to the 121GW.  The 121GW measures the value as...... well it doesn't even recognise there is a value.  I then put the probes back into the Owen and it is measuring the same.  All I get out of the 121GW is OF.L. Not good for a meter costing 10-15 times the amount. 



cowasaki:
And I've just plugged it in again and it seems to be working.  I'm been having these issues from day 1 but as I have over ten meters I've not got round to doing anything with it.......

dcac:
You seem to have the 121gw in Continuity mode and not in Ohms mode - Continuity can only measure up to 500.00 ohms.

? I switch to ohms and it was the only resistance mode that came up.  Do I have to change something else?  That doesn't seem very intuitive.  What tells you it's in continuity mode?
